If you can get a decent deal on a 1TB console, it's certainly worth the effort as new-gen games have massive mandatory installs, often upto 50GB, so you can see the space easily get swallowed up within six months or so. With the like of Halo 5, Rise of the Tomb Raider, Forza 6, Titanfall and Sunset Overdrive to enjoy, you'll be well on your way.
